Bulb Lasagna: A Recipe for Lasting Spring Color

layers of spring bulbs in a pot

This weekend promises to be beautiful weather for some final gardening chores. Guarantee yourself weeks of spring blooms by making “bulb lasagna.” Line the bottom of a 14″ or deeper container with gravel for drainage. Then layer potting soil and bulbs in 3 layers, starting with the largest bulbs on the bottom. Choose bulbs which will flower at different times to make your planting really work.  Keep in mind that there will likely be some overlap in bloom times, so choose a color scheme that will be pleasing, such as monchromatic, contrasting, warm or cool colors.
